The wall of kindness (Persian: دیوار مهربانی‎‎ dīvār-e mehrabānī; Urdu: دیوار مہربانی‎ Dewar e meherbani) is a charity work phenomenon and a kind of welfare, usually done by attaching cloth hangers from outside of houses; those encourage people to donate miscellaneous useful things such as winter clothing. It was introduced by an anonymous Iranian, and the practice quickly spread throughout the country. The motto of the movement are two sentences which appear on the walls: "leave if you do not need" (نیاز نداری بگذار) and "take if you need" (نیاز داری بردار).
